ATTACHMENT FOR PUMPS.

SPECIFICATION forming part of Letters Patent No. 426,814, dated April29, 1890. Application filed October 28, 1889- Serial No. 328,434. (Nomodel.)

To all whom it may concern.-

Be it known that 1, WILLIAM W. Home, a citizen of the United States,residing at Lansing, in the county of Ingham and State of Michigan, haveinvented certain new and useful Improvements in Attachments for Pumps,of which the following; is a specification, reference being had thereinto the accompanying drawings.

This invention relates to new and useful improvements in attachments forpumps; and the invention consists in the peculiar construction of atreadle-connection adapted to be attached to the handle of the pump,whereby the power of the operator may be exerted to the best advantage,so that a large volume of water may be pumped with the least possibleexertion on the part of the operator from deep wells or from shallowwells with large pump-cylinders; and, further, the invention consists inthe peculiar cont-ruction of a rock-shaft journaled upon the platformand connected to the handle of the pump, and of treadle-levers appliedthereto, whereby the weight of the operator may be used as beforementioned, and, further, in the peculiar construction, arrangement, andcombination of these various parts, and, further, in the peculiarconstruction of a movable fulcrum for said pump-lever, all as more fullyhereinafter described. 7

The handle shown herein I have embodied in a separate application forpatent filed December 1t, 1389, Serial No. 333,807.

In the drawings which accompany this specification, Figure 1 is a sideelevation of my improvement as applied to a pump. Fig. 2 is a plan Viewthereof. Fig. 3 is a cross-section thereof on line w 00 in Fig. 1. Fig.4 is a perspective view from the under side, showing the manner ofadjusting the fulcrum.

A is a pump-head of any desired construction, having the handle B. Thishandle may be pivoted in the usual manner upon the pump-head itself, orit may be pivoted upon the adjustable fulcrum 0, consisting of uprightarms pivoted at D to the platform, and secured by means of the pivot-pinD, passing through the lugs E, which depend from the adjustable endlever, which is secured upon the pump-handle D in its adjusted positionby means of the set-screw F, the adjustable lever being of such shape asto be adapted to be sleeved upon the handle 13, the cross-bars G and Gforming guides on the lower side.

H is a pin secured, after the parts are engaged as above described, inthe lower side of the handle B in the rear of the cross-bar G to preventthe accidental separation of the parts.

I is a rock-shaft j ournaled in the standards J and J, which extendupwardly from the base K. This rock-shaft is provided at its forward endwith the crank-arm L and at its other, end with the cross-head M, whichis provided at its end with the treadles N. These treadles I preferablysecure to the cross-head pivotally by means of the pivots a, and soconstruct the parts that the plane of these treadles is almost on thehorizontal, so that the foot of the operator may not be turned in theuse of the device. This may be accomplished in a number of ways; but Ipreferably do it by securing an auxiliary cross-bar O pivotally upon thestandard J and secure the lower end of the treadlearms b in the ends ofthe auxiliary cross-bar O. Y

P is a connecting-rod secured at its upper end in the lugs P on theadjustable portion E of the handle. It is evident that in using thisdevice with an ordinary pump-handle".

this maybe pivotally connected to the handle in any suitable manner. Atits lower end this connecting-rod is secured to the end of the crank-armL.

Q is a spiral spring sleeved upon the rockshaft I, secured at one end tothe standard J and at the other end to the nut R, which is looselysleeved upon the shaft and provided upon its inner face with theserrations or teeth R, which engage with similar serrations or teethupon the stationary abutment on the shaft. The tension of this springacts downward upon the crank L, and may be increased or diminished byturning the nut R to the right or left, the tension of the springQholding the serrations or teeth into engagement with the teeth on thestationary abutment S to prevent its turning out of its adjustedposition. I preferably arrange suitable span ner-holes S in the nut Rfor turning it, although this may be effected by making a hexagon orsquare nut and turning it by means of a wrench. It is obvious that whileI show this peculiar construction of bringing the spring-pressure tobear downward upon the crank L, and through the connection P upon thelever of the pump, any construction which acts downwardly with itstension upon the connecting-rod P will effect the desired end.

The parts being thus constructed and arranged, they are intended tooperate as follows: The ad 3' ust-able hand-1ever E is moved in or outthe desired distance to be easilyoperated by the person doing thepumping. The operator now steps upon the treadles N and N, bearing withhis weight first upon the treadle N, and at the same time raising withhis hands the pump-handle. lhe effect of this would be to lower theplunger of the pump and raise the connecting-rod P, and with it thecrank L and treadle N, to which are connected the ends of the spring Q,acting against the resiliency of the spring. The operator now transfershis weight upon the treadle N, pulling downward with his hands upon thepump-handle, raising the plunger of the pump, in which he is aided bythe spring tending to resume its normal position.

It will be seen that by means of the treadlelever I being connected toboth the cross-head M and the auxiliary cross-heads O the face of thetreadles are always maintained in a horizontal position, therebypreventing any inconvenient twisting of the feet of the operator.

Should the tension of the spring not be proper, it may be increased ordiminished to suit the operator by turning the crank-handles S to raiseor lower the center of the sprin What I claim as my invention is--- 1.In combination with a pump and its in presence of two witnesses,

handle, a rock-shaft journaled below said handle having a crank-armthereon, a rod connecting the handle with the crank-arm, a cross-headrigidly secured on the shaft, and a spring on the shaft stationarilysecured at one end to a suitable standard and adjustably secured to theshaft at its outer end, substantially as described.

2. In combination with a pump and its handle, a rock-shaft journaledbelow said handle, a rod connecting the handle with a crank 011 saidshaft, a treadle-bar or cross-head at the other end of said shaft, and aspring sleeved upon the shaft and stationarily secured at one end and atthe other end secured upon the adjustable nut R, engaging against thestationary abutment S, substantially as described.

3. In combination with a pump and its handle, the adjustable fulcrum G,pivotally se' cured upon the platform at its lower end and at its upperend in the ears E of the sliding hand-lever E, the cross-bars G and G,the set-screw F, and the pin II, substantially as described.

4. In combination with a pump and its handle, a treadle attachmentadapted to be secured thereto, consisting of the following elements: thebase K, having standards J and J,

I rock-shaft I, having crank L, cross-head M,

and treadles N and N, the auxiliary cross-' head 0 and treadle-bars Z),the spring Q, nut R, abutment S, and connecting-rod I, the parts beingarranged to operate substantially as and for the purpose described.

In testimony whereof I affix my signature, this 17 th. day of October,1889.
